ObjectiveTo evaluate the effect of Ningying Formula (宁瘿方) combined with low-dose antithyroid drugs (ATDs) on the relapse risk for patients with Graves' hyperthyroidism (GH) during the remission phase, and to analyze the related factors between GH relapse and thyrotropin receptor antibody (TRAb) negativity, so as to provide evidence for the standardized management of GH in remission stage. MethodsA single-center retrospective cohort study was conducted, including 269 GH patients in the remission stage. After propensity score matching (PSM), 102 matched pairs (204 patients) were established. The control group received low-dose ATDs as maintenance therapy, while the exposure group received the core Ningying Formula in addition to low-dose ATDs. The primary outcome was the GH recurrence rate; the secondary outcome was the thyrotropin receptor antibody (TRAb) negativity rate (TRAb<1.75 IU/L). Safety outcomes included treatment-related adverse events. Differences between groups were assessed using Cox regression models and Kaplan-Meier curves, with sensitivity analysis performed using inverse probability of treatment weighting (IPTW). ResultsThe median follow-up in the matched cohort was 28.07 months. Regarding the GH recurrence outcome, the recurrence rate in the exposure group (18/102, 17.6%) was significantly lower than that in the control group (31/102, 30.4%; χ²=4.539, P=0.033); regarding the TRAb negativity outcome, the TRAb negativity rate in the exposure group (50/102, 49.0%) was significantly higher than that in the control group (23/102, 22.5%; χ²=15.551, P<0.001). Multivariate Cox regression analysis for recurrence showed that Ningying Formula treatment reduced the risk of recurrence [HR=0.324, 95%CI(0.170, 0.617), P<0.001]. Male [HR=2.209, 95%CI(1.079, 4.520), P=0.030], higher initial TRAb level [per 1 IU/L increase: HR=1.033, 95%CI(1.003, 1.064), P=0.032], and larger thyroid volume [per 1 ml increase: HR=1.045, 95%CI(1.003, 1.088), P=0.035] were identified as independent risk factors for recurrence; multivariate Cox regression analysis for TRAb negativity indicated that Ningying Formula treatment promoted TRAb negativity [HR=1.826, 95%CI(1.091, 3.056), P=0.022], while a higher initial TRAb level was associated with a lower probability of negativity [HR=0.974, 95%CI(0.950, 0.998), P=0.032]. Survival analysis showed significant differences in relapse rate between groups (Log-Rank P=0.003) and in TRAb outcomes (Log-Rank P=0.034). The incidence of treatment-related adverse events was similar between groups (P=0.757). The IPTW sensitivity analysis was consistent with the primary analysis, indicating robust results. ConclusionThe Ningying Formula combined with low-dose ATDs can significantly reduce the risk of recurrence and can improve the TRAb negativity rate in GH patients during the remission stage, without increasing common adverse events, making it an optional strategy for reducing relapse risk during remission. Male gender, higher baseline TRAb level, and larger thyroid volume indicate a higher risk of recurrence, warranting focused follow-up and stratified management.

ObjectiveTo investigate the mechanism by which the Zishen Huoxue prescription (ZSHXP) ameliorates cognitive dysfunction in rats with vascular dementia (VD) induced by the bilateral common carotid artery ligation (2-VO model rats) through regulating the glucose-regulated protein 78 (GRP78)/protein kinase R-like endoplasmic reticulum kinase (PERK)/activating transcription factor 4 (ATF4) signaling pathway. MethodsA VD rat model was established via the 2-VO method. A total of 72 male Sprague-Dawley (SD) rats were randomly divided into six groups: Sham group, Model group, donepezil hydrochloride group (0.45 mg·kg-1), and ZSHXP groups at low (8.90 g·kg-1), medium (17.80 g·kg-1), and high (35.60 g·kg-1) doses,with 12 rats in each group. The Morris Water Maze test was utilized to assess spatial learning and memory abilities of rats, and the Novel Object Recognition test was used to evaluate cognitive performance. Hematoxylin-eosin (HE) and Nissl staining were applied to observe the histological and morphological changes in hippocampal tissues. Transmission electron microscopy (TEM) was used to observe the morphological changes of endoplasmic reticulum in rat hippocampal neurons. Immunofluorescence staining was adopted to detect the colocalization of neuronal nuclei antigen (NeuN) with GRP78 and βⅢ Tubulin with gasdermin D (GSDMD) in hippocampal neurons. Western blot was used to detect the expression levels of endoplasmic reticulum stress (ERS)-related proteins including GRP78, PERK, ATF4, phosphorylated protein kinase R-like endoplasmic reticulum kinase (p-PERK), C/EBP homologous protein (CHOP), NOD-like receptor protein 3 (NLRP3), Caspase-1 and GSDMD. ResultsCompared with the sham operation group, the model group showed a significantly prolonged escape latency (P<0.01), a significant decrease in the number of platform crossings and the residence time in the target quadrant (P<0.01), and a markedly reduced recognition index (P<0.01). Histological observations revealed that the hippocampal neurons in the model group were disorderly arranged with reduced quantity, deformed and shrunken cell bodies, and pyknotic and hyperchromatic nuclei. The number of Nissl bodies decreased significantly. The number of endoplasmic reticula reduced obviously, accompanied by abnormal dilation and swelling, and the loss of normal folding structure. The fluorescence colocalization of NeuN with GRP78 and βⅢ Tubulin with GSDMD in the hippocampus was significantly increased in the model group. The protein expression levels of GRP78, p-PERK/PERK, ATF4, CHOP, NLRP3, GSDMD and Caspase-1 in the model group were significantly elevated (P<0.01). Compared with the model group, the donepezil hydrochloride group and the ZSHXP medium- and high-dose groups had a significantly shortened escape latency (P<0.01) and an increased number of platform crossings (P<0.05, P<0.01). The residence time in the target quadrant was increased in the donepezil hydrochloride group and all ZSHXP groups (P<0.05, P<0.01), with a significantly improved recognition index (P<0.01). In the donepezil hydrochloride group and all ZSHXP groups, the number of hippocampal neurons increased with a more compact arrangement and reduced nuclear hyperchromasia. The number of Nissl bodies increased with morphological structures tending to be normal. In the ZSHXP high-dose group, the number of endoplasmic reticula increased and the folding structure was restored. The fluorescence colocalization of NeuN with GRP78 and βⅢ Tubulin with GSDMD in the hippocampus was significantly weakened in the treatment groups. In the donepezil hydrochloride group, the protein expressions of GRP78, ATF4 and CHOP were increased (P<0.01), while the expression of p-PERK/PERK was decreased (P<0.05). In the ZSHXP low-dose group, the expressions of GRP78, p-PERK/PERK and CHOP were elevated (P<0.05, P<0.01). The ZSHXP medium- and high-dose groups showed a significant decrease in the protein expressions of p-PERK/PERK, ATF4 and CHOP (P<0.01), and the high-dose group had a markedly reduced GRP78 protein expression (P<0.01). In the donepezil hydrochloride group, the Caspase-1 protein expression was increased (P<0.01) and the NLRP3 protein expression was decreased (P<0.01). In the ZSHXP low-dose group, the GSDMD expression was elevated (P<0.01) while the NLRP3 protein expression was reduced (P<0.01). After treatment with medium and high doses of ZSHXP, the protein expression levels of NLRP3, GSDMD and Caspase-1 were significantly decreased (P<0.01). ConclusionThe ameliorative effect of ZSHXP on cognitive function in 2-VO model rats may be associated with its regulation of the GRP78/PERK/ATF4 signaling pathway, which ameliorates ERS and inhibits neuronal pyroptosis.

Diabetic retinopathy(DR)remains the leading cause of vision loss in patients with diabetes. Current anti-vascular endothelial growth factor(VEGF)therapies are limited by inadequate response in some patients and the necessity for repeated intravitreal injections, underscoring the urgent need for novel therapeutic targets. Angiopoietin-like protein 4(ANGPTL4), a multifunctional secreted protein, has emerged as a critical regulator in the pathogenesis and progression of DR, positioning it as a promising interventional target. This review systematically elaborates the biological characteristics of ANGPTL4, with a focus on its expression dynamics, molecular mechanisms, and regulatory networks rolesin the development of DR. Furthermore, the prospects of ANGPTL4-targeted therapeutic strategies are discussed, aiming to offer new insights and directions for understanding DR pathogenesis, advancing multi-target drug development, and improving clinical management.

Objective:To investigate the survival outcomes and prognostic factors in patients undergoing radical resection for pancreatic body and tail cancer.Methods:A retrospective case series study was conducted on 992 patients who underwent radical resection for pancreatic body and tail cancer at the Pancreatic Center of the First Affiliated Hospital of Nanjing Medical University from January 2016 to June 2024. In this study, 577 (58.2%) were male and 415 (41.8%) were female,with an age of (65±9) years (range: 26 to 86 years). Follow-up continued until June 2024. Survival rates were estimated using the Kaplan-Meier method,and prognostic factors were identified using univariate and multivariate Cox proportional hazards models.Results:Among 992 patients,open surgery was the predominant approach (89.1%, 884/992), and radical antegrade modular pancreatosplenectomy (RAMPS) was performed in 317 patients (32.0%). Combined organ resection,venous resection,and arterial resection were performed in 23.5%, 9.3%,and 11.2% of patients,respectively. The rates of R0, R1-1 mm, and R1-direct resections were 49.8% (494/992),41.5% (412/992), and 8.7% (86/992),respectively. Stage ⅡB was the most common TNM stage (32.2%,319/992). A total of 801 patients (80.8%) received adjuvant chemotherapy. The median follow-up period was 32.0(8.8) months(range:3.2 to 105.3 months),during which 508 patients (51.2%) died. The overall median survival (OS) was 26.4 months,with 1-,3-, and 5-year survival rates of 79.0%,40.0%, and 29.0%, respectively. In the recent five years (from 2020 to 2024), the median OS improved significantly to 34.1 months compared to 20.0 months from 2016 to 2019 ( P<0.01). Histological subtype analysis showed that the median OS time was 26.7 months for pancreatic ductal adenocarcinoma (PDAC, n=855),58.9 months for invasive intraductal papillary mucinous carcinoma (IPMC, n=32),and 15.7 months for adenosquamous carcinoma of pancreas (ASCP, n=73) ( P=0.001). Among PDAC patients, adjuvant chemotherapy significantly improved survival (29.1 months vs. 14.4 months, P<0.01);in IPMC patients, adjuvant chemotherapy also extended survival (65.7 months vs. 58.9 months, P=0.047). Although ASCP patients receiving chemotherapy had a longer median OS time than those without (18.8 months vs. 8.9 months),the difference was not statistically significant ( P=0.151). Multivariate Cox regression analysis in PDAC patients indicated that adjuvant chemotherapy, R0 resection, T stage,N stage,and tumor differentiation were independent prognostic factors ( P<0.01). The median OS time by TNM stage was:not reached for stage ⅠA, 51.6 months for ⅠB, 25.5 months for ⅡA, 23.7 months for ⅡB, 23.0 months for Ⅲ, and 14.4 months for Ⅳ. The median OS time for R0,R1-1 mm,and R1-direct resections was 34.1,24.7,and 15.7 months,respectively ( P<0.01). Conclusion:Adjuvant chemotherapy,R0 resection,tumor stage,and differentiation are independent prognostic factors for pancreatic body and tail cancer.

Intraoperative cell salvage (IOCS) has been widely applied as an important blood conservation measure in surgical operations. However, there is currently a lack of clinical practice guidelines for the implementation of IOCS in patients with malignant tumors. This report aims to provide clinicians with recommendations on the use of IOCS in patients with malignant tumors based on the review and assessment of the existed evidence. Data were derived from databases such as PubMed, Embase, the Cochrane Library and Wanfang. The guideline development team formulated recommendations based on the quality of evidence, balance of benefits and harms, patient preferences, and health economic assessments. This study constructed seven major clinical questions. The main conclusions of this guideline are as follows: 1) Compared with no perioperative allogeneic blood transfusion (NPABT), perioperative allogeneic blood transfusion (PABT) leads to a more unfavorable prognosis in cancer patients (Recommended); 2) Compared with the transfusion of allogeneic blood or no transfusion, IOCS does not lead to a more unfavorable prognosis in cancer patients (Recommended); 3) The implementation of IOCS in cancer patients is economically feasible (Recommended); 4) Leukocyte depletion filters (LDF) should be used when implementing IOCS in cancer patients (Strongly Recommended); 5) Irradiation treatment of autologous blood to be reinfused can be used when implementing IOCS in cancer patients (Recommended); 6) A careful assessment of the condition of cancer patients (meeting indications and excluding contraindications) should be conducted before implementing IOCS (Strongly Recommended); 7) Informed consent from cancer patients should be obtained when implementing IOCS, with a thorough pre-assessment of the patient's condition and the likelihood of blood loss, adherence to standardized internally audited management procedures, meeting corresponding conditions, and obtaining corresponding qualifications (Recommended). In brief, current evidence indicates that IOCS can be implemented for some malignant tumor patients who need allogeneic blood transfusion after physician full evaluation, and LDF or irradiation should be used during the implementation process.

Laparoscopic subtotal cholecystectomy (LSC) has been a safe and viable alternative to conversion to laparotomy in cases of severe cholecystitis. The objective of this study is to determine the utility of intraoperative choledochoscopy in LSC for the exploration of the gallbladder, cyst duct, and subsequent stone clearance of the cystic duct in cases of severe cholecystitis. A total of 72 patients diagnosed with severe cholecystitis received choledochoscopy-assisted laparoscopic subtotal cholecystectomy (CALSC). A choledochoscopy was performed to explore the gallbladder cavity and/or cystic duct, and to extract stones using a range of techniques. The clinical records, including the operative records and outcomes, were subjected to analysis. No LSC was converted to open surgery, and no bile duct or vascular injuries were sustained. All stones within the cystic duct were removed by a combination of techniques, including high-frequency needle knife electrotomy, basket, and electrohydraulic lithotripsy. A follow-up examination revealed the absence of residual bile duct stones, with the exception of one common bile duct stone, which was extracted via endoscopic retrograde cholangiopancreatography. In certain special cases, CALSC may prove to be an efficacious treatment for the management of severe cholecystitis. This technique allows for optimal comprehension of the situation within the gallbladder cavity and cystic duct, facilitating the removal of stones from the cystic duct and reducing the residue of the non-functional gallbladder remnant.

OBJECTIVE:
Acupuncture therapies are known for their effectiveness in treating a variety of gastric diseases, although the mechanisms underlying these effects are not fully understood. This study tested the effectiveness of electroacupuncture (EA) at acupoints Zhongwan (RN12) and Weishu (BL21) for managing gastric motility disorder (GMD) and investigated the underlying mechanisms involved.
METHODS:
A GMD model was used to evaluate the impact of EA on various aspects of gastric function including the amplitude of gastric motility, electrogastrogram, food intake, and the rate of gastric emptying. Immunofluorescence techniques were used to explore the activation of spinal neurons by EA, specifically examining the presence of cholera toxin B subunit (CTB)-positive neurons and fibers emanating from acupoints RN12 and BL21. The stimulation of γ-aminobutyric acid (GABA)-ergic neurons in the spinal dorsal horn, the inhibition of sympathetic preganglionic neurons in the spinal lateral horn, and their collective effects on the activity of sympathetic nerves were examined.
RESULTS:
EA at RN12 and BL21 significantly improved gastric motility compromised by GMD. Notably, EA activated spinal neurons, with CTB-positive neurons and fibers from RN12 and BL21 being detectable in both the dorsal root ganglia and the spinal dorsal horn. Further analysis revealed that EA at these acupoints not only stimulated GABAergic neurons in the spinal dorsal horn but also suppressed sympathetic preganglionic neurons in the spinal lateral horn, effectively reducing excessive activity of sympathetic nerves triggered by GMD.
CONCLUSION
EA treatment at RN12 and BL21 effectively enhances gastric motility in a GMD model. The therapeutic efficacy of this approach is attributed to the activation of spinal neurons and the modulation of the spinal GABAergic-sympathetic pathway, providing a neurobiological foundation for the role of acupuncture in treating gastric disorders.

OBJECTIVE:
Varied acupoint selections represent a potential cause of the uncertainty surrounding the efficacy of acupuncture for knee osteoarthritis (OA). Skin temperature, a guiding factor for acupoint selection, may help to address this issue. This study explored thermal sensitization of acupoints used for the treatment of knee OA.
METHODS:
This cross-sectional case-control study enrolled cases aged 45-75 years with symptomatic knee OA and age- and gender-matched non-knee OA controls in a 1:1 ratio. All participants underwent infrared thermographic imaging. The primary outcome was the relative skin temperature of acupoint (STA), and the secondary outcome was the absolute STA of 11 acupoints. The Z test was used to compare the relative and absolute STAs between the groups. Principal component analysis was used to extract the common factors (CFs, acupoint cluster) in the STAs. A general linear model was used to identify factors affecting the STA in the knee OA cases. For the group comparisons of relative STA, P < 0.0045 (adjusted for 11 acupoints through Bonferroni correction) was considered to indicate statistical significance. For other analyses, P < 0.05 was used as the threshold for statistical significance.
RESULTS:
The analysis included 308 participants, consisting of 151 cases (mean age: [64.58 ± 6.67] years; male: 25.83%; mean body mass index: [25.70 ± 3.16] kg/m2) and 157 controls (mean age: [63.37 ± 5.96] years; male: 26.11%; mean body mass index: [24.47 ± 2.84] kg/m2). The relative STAs of ST34 (P = 0.0001), EX-LE2 (P < 0.0001), EX-LE5 (P = 0.0006), SP10 (P < 0.0001), BL40 (P = 0.0012) and GB39 (P = 0.0037) were higher in the knee OA group. No difference was found in the STAs of ST35, ST36, SP9, GB33 and GB34. Four CFs were identified for relative STA in both groups. The acupoints within each CF were consistent between the groups. The mean values of the relative STAs across each CF were higher in the knee OA group. In the knee OA cases, no factors were observed to affect the relative STA, while age and gender were found to affect the absolute STA.
CONCLUSION
Among patients with knee OA, thermal sensitization occurs in the acupoints of the lower extremity, exhibiting localized and regional thermal consistencies. The thermally sensitized acupoints that we identified in this study, ST34, SP10, EX-LE2, EX-LE5, GB39 and BL40, may be good choices for the acupuncture treatment of knee OA.
